Tide of change

Does it come,
Crashing
Sweeping your feet from beneath you,
Knocking your breath from you.

Do you try to escape,
Evading
Constantly shifting up the beach
Till the sand disappears.

Do you fight it,
Fortifying
Building and rebuilding doggedly
With the defiance of Canute.

Or do you turn,
Realising
That you are already ankle deep,
That the change is already here.
